Abstract

The compounds of the formula (I) ##STR1## in which X denotes CH.sub.2, O, S or NR.sup.6, PA1 R.sup.1 denotes alkyl, cycloalkyl, alkenyl, (substituted) phenyl, or (substituted) naphthyl, PA1 R.sup.2 and R.sup.3 denote alkyl, alkenyl or phenyl, or R.sup.2 and R.sup.3 together denote an alkylene chain, PA1 R.sup.4 denotes --H, --CN, --CCl.sub.3, --C.tbd.CH, alkyl, F, or --C(S)--NH.sub.2, PA1 R.sup.5 denotes pyridyl, furyl, thienyl, phthalimidyl, di(C.sub.1 -C.sub.4)alkylmaleinimidyl, thiophthalimidyl, dihydrophthalimidyl or tetrahydrophthalimidyl, which may all be substituted, or substituted phenyl, or PA1 R.sup.4 and R.sup.5 --together with the carbon atom bridging them--denote an optionally substituted indanyl, cyclopentenoyl or cyclopentenyl radical, with the proviso that compounds of the formula I in which PA1 R.sup.1 denotes phenyl which is substituted in the para-position by (C.sub.1 -C.sub.4)alkoxy, halogen or (C.sub.1 -C.sub.4)alkyl; PA1 R.sup.2 and R.sup.3 denote CH.sub.3 ; PA1 X denotes O; PA1 R.sup.4 denotes H and PA1 R.sup.5 denotes 3-phenoxyphenyl or (4-fluoro-3-phenoxy)phenyl being excepted, have advantageous insecticidal, acaricidal and nematocidal properties.
